due to the fact that the majority of sets were on the under side, as 

 previously parasitized forms had been observed on the upper side of 

 the leaf. A few of the parasitized sets showed the holes through which 

 the adults had emerged, so that at this time the parasites were emerg- 

 ing out of doors. 



August 1st and 3d, again visited Newark, and on the latter date also 

 Montclair, East Orange and Passaic. In the latter place there are 

 comparatively few soft maples, but some of these showed a slight 

 infestation. In Newark some of the infested leaves showed quite a 

 number of parasitized scales, while others were light in color, showing 

 that the parasite within them was in the larval stage. On one leaf an 

 adnlt parasite was seen running about. 



In East Orange I did not observe any CoccinelUds, while in Mont- 

 clair and Newark there were not nearly so many as at the previous 

 examination. In both places I found a single beetle in a dry, curled- 

 up leaf, as if in hiding. A few days later a few sets, some of which 

 were parasitized, were observed on linden and osage orange in Newark.

August 11th, some leaves were collected from an infested tree in 

 New Brunswick. There seemed to be few cottony Qgg masses on the 

 twigs and branches, but the leaves were pretty well set ^vith the young. 

 On one of them I observed a parasite which seemed to be ovipositing 

 in the good scales. It was also noted that' some of the scales were 

 slightly narrower than others, and npon examination it was found
